TRANSLATING DEVICE.

Application filed December 18, 1913.

To all whom it may concern Be it known that we, IVILLIAM R. SORGEL and VILLIAM H. GAULKE, are citizens of the United States, residing at Milwaukee, in the county of Milwaukee and State of WVisconsin, have invented a certain new and useful Improvement in Translating Devices, of which the following is a full, clear, concise, and exact description. reference being had to the accompanying drawings, forming a part of this specification.

Our invention relates to systems of and means for operating electrical percussion devices such as hammers, for instance.

Our invention contemplates the electric operation and suitable control of a reciproeating element which can of course be variously applied; we wish it understood of course that while as stated the reciprocating element can be applied to vibrators, flashers, hammers or in fact to any use requiring a reciprocating element, that we do not wish to be limited by the following description of our system and device herein, in which description we particularly allude to hammers and show our device and system as arranged more particularly to such 'an electrically controlled hammer device.

It is a prime object of our. invention to so arrange a system of control of a reciprocating element that it may be used to reciprocate rapidly between limiting positions without causing undue sparking of the electrical elements or devices utilized in the control. In the specific form of the invention herein disclosed we have also so arranged the system that it can be interchangeably applied to both alternating and direct current sources of current supply without causing any difficulty, and it may thus be considered more or less of a universal device.

e will now explain specifically one form of arranging a system and constructing a device in accordance with our invention, by referring to the accompanying drawings in which:

Figure 1 is a side view of an electric hammer constructed in accordance with our in vention; Fig. 2 is a side view at right angles to Fig. 1; Fig. 3 is a modified form of this Specification of Letters Patent.

Serial No. 807,412.

\Ve will explain first a specific form of hammer which is applicable in accordance with our invention by referring to Figs. 1 and 2 in which we have two coils of wire or solenoids 1 and 2 respectively which are held within a magnetic frame work 3 substan- The solenoids of course have hollow interiors to accommodate a plunger 4, which plunger has a tail piece 5 operating within a guide 6, which guide may" be provided on its exterior with a screw threaded portion 7 to accommodate a handle 8. The plunger of course can reciprocate to and fro within the space provided for it "and is adapted tostrike a sliding tool carrier 9 slidably mounted within a bearing 10 provided in the magnetic framework 3. The tool carrier 9 is provided with a tapered shank 11.to accommodate any desired tool such as a hammer that may be fastened thereto.

Inthe operation of the device then, as is readily understood, the whole structure is placed, say vertically, upon the nail or other element which it is desired to strike and current supplied alternately to the solenoids 1 and 2, thereby to cause reciprocation of the plunger 4 and strike blows against the tool carrier 9, thus striking the nail. In this position, of course, the tool carrier 9 has been pushed toward the left (Fig. 1) by being held tightly against the nail, or by resting upon it if the device is in a vertical position. In Fig. 3 the structures are much the same except that the magnetic framework 3 is made in two parts and is substantially elliptical and serves entirely to inclose the coils, thus to better protect the devices within as is readily understood.

Referring more particularly to Fig. 4, we show the device of Fig. 1 in combination with a motor generator consisting of the fields 12, 12 and armature 13. The armature is provided with "customary collector rings 14, 15 and the commutator 16 having brushes 17 and 18.. Leading in wires 19 and 20 are connected respectively to the collector rings 14 and 15, and leading in wires 21 and 22 are connected respectively to the brushes 17 and 18. Av switch 23 may connect the wires 19 and 20 with an alternating source of current'supply 24, or a switch 25 may connect the wires 21 and 22 with a'direct source of current supply 26. The solenoid 1 is connected by means of the conductor 27 to the brush 17, and the solenoid 2 has one of its terminals connected by means of the conductor 28 to the brush 18. The two remaining terminals of the solenoids are connected together and then connected by means of a conductor 29 with the collector ring 14: preferably possibly through the" 31 is under the brush 18 then a short circuit exists between the brush 18 and the collector ring 14, thence to the conductor 29. From this it will be seen that as the armature 13 rotates, conductors 27 and 29 are first short circuited and then conductors 28 and 29, and this goes on periodically. Assume now that the switch 25 is closed so that current is supplied to the armature 13 from the source 26 then current is supplied to the two solenoids 1 and 2 in series. The armature however is also rotated and as this armature is rotated, the establishing of a short circuit alternately between conductors 27 and 29 and conductors 2S and 29, deprives one or the other of the solenoids of current, thereby having the solenoids 1 and 2 alternatively energized to alternatively attract the plunger 4. It will of course be understood that the showing is more or less diagrammatic. In this way the plunger is reciprocated to violently hit the tool carrier and thus cause the percussions desired. Now should the switch 25 be open however, and the switch 23 closed, then alternating cm rent would be supplied to the collector rings 14 and 15 which would become direct current at the brushes 17 and 18, thus again supplying current to the solenoids 1 and 2 serially except at those times when one or the other of the solenoids is bridged by a short circuit. In thus operating the device We find that we are enabled to cause a proper reciprocation of the plunger 4 without the attendance of injurious sparking at any of the switching points, the brushes for instance, and thus are enabled to operate a hammer satisfac-- torily indefinitely at a very low consumption of power.

The specific illustration herein contem plates a motor generator so that the apparatus may be used either for a direct current or alternating source of current supply, but it will be readily understood of course that similar conditions can be supplied without the resort to the particular motor generator arrangement as herein disclosed, sufiice it to say that this particular arrangement is one of many that will cause a reciprocation of the device without the sparking or other injurious effects, which may ordinarily attend the rapid change of circuit connections incident to the operation of a reciprocating device such as contemplated herein. A spring 10 normally tends to retract the tool carrier 9; and a spring 5 serves as a cushion for the recoil of the plunger and to assist in its starting.

It will of course be readily apparent that the reciprocating element itself does not necessarily form part of the invention, as the invention would contemplate broadly the rapid alternate energization of the two solenoids to perform any other function, which solenoids or other coils may be called upon to perform. It will of course be also understood that in some forms of the invention but one solenoid might answer the purpose to be used in connection with any suitable form of retractile means, if so desired.

From what has been described it is thought the nature of our invention will be readily clear to those skilled in the art, and it will also be clear that many changes and modifications may be made without departin from its spirit.

Tiaving however thus described one form which our invention may take, what we claim as new and desire to secure by Letters Patent is:
